Once installed as a module for the webserver, WebDNA looks for two things:

- the .dna extension for your WebDNA pages
- The html comment  at the top of your WebDNA pages

Is this mandatory? No, you can override these requirements in the settings. But for now, let's use .dna as the extension and put  at the top of the pages.

A basic WebDNA tag is [date]. Note the syntax: the WebDNA language is built to understand square brackets.

Create a page named "test.dna" in your root webserver (on a Mac, this is /Library/WebServer/Documents/) and enter the following code:

 [date]

That's it! Using your browser, call your local server with this address:

http://127.0.0.1/test.dna

You should see today's date.

Simple, isn't it? What if you want another date format? Try this: [date %A, %B %d, %Y]. This will show the day, month, date and year in the format of Thursday, August 14, 2012. You will find all the date formats here
